WebBinary Relation on a Set (cont.) Question: How many relations are there on a set A? Solution: Because a relation on A is the same thing as a subset of A ⨉ A, we count the subsets of A × A.Since A × 2A has n elements when A has n elements, and a set with m elements has 2m subsets, there are subsets of A × A.Therefore, there are relations on a …
